Your best bet would be to use a PDF printer like CutePDF Writer (free). It installs as a printer on your Windows computer, and then you can print the directions in Google Maps straight to the CutePDF printer, which will let you save the file as a PDF.

But i want to download the magnified version of map not just one small image

You can click the blue Maps link at the top of the page to show a small map for each step of the directions. Checkmarking the Include large map at the top (just to the left of the Print button) will show a large map of the whole trip in the print out.
